CONCRETE BUILDING STRUCTURE.

applicati@ filed may 1e, 1922. serial no. 561,441.

To all 'whom t may concern:

Be it known that VAN @RAN JEFFRIES, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, has invented certain new and useful Improvements in Concrete Building Structures, of which the following is a specification.4

The present invention is directed to improvements in concrete building structures, and has for its primary object to provide a wall so constructed as to produce -a hollow chamber, which serves as an air space for excluding dampness.

A further object of the invention is to provide a wall structure of this nature so formed that portions of the supporting posts will project inwardly beyond the plane of the inner surface of the wall so as to permit the application of laths, the outer faces of the posts being completely imbedded in the wall. Y e l A. still further object of the invention is to provide novel means, in the form of a wire truss, to retain the posts in their proper position during the time the wall is being poured.

Still another object of the invention is to provide a novel form of mold to be used in producing a wall wherein an air space is provided by the plaster and laths, and the innerl face of the cement wall, whereby an air space is produced.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combination of elements and arrangements of parts, and hereinafter'to be fully described and pointed out in the appended claims.

In thel accompanying drawing:

Figure 1 is a longitudinal sectional view showing the manner in which the mold isv arranged previous to pouring the cement.'

Figure 2 is a horizontal sectional view through a corner of the wall, showing the relative arrangement of the corner posts, and after the' wall has been poured.

Figure '3 is a section-al view on line 3-3 0f Figure 1. Y

Figure 4 is a vertical sectional view taken through a section ofthe wall showing means to permit free circulation of ai-r in the air space.

Figure v5 is a horizontal sectional view through a section of the wall, showing a `sli htly modified form of the invention.

eferring to the drawing, and particularly to Figure 1 thereof, there is shown a pair of vertically arranged posts l, which may be supported in any well known manner upon a suitable foundation (not shown), said posts being provided at suitable points with spaced .transverse bores 2, the purpose of which will appear later.

Fixed to the opposite sides of the posts l are dovetailed vertically disposed strips 3, said strips being arranged between the bores 2. The wire tie 4consists of two strands 5 of suitable gage wire, portions of which are engaged in the bores 2. It is obvious that upon placing a bar or any suitable tool between the strands 5, and rotating the same that the strands will be twisted into mutual engagement, thus connecting the posts 1 in a rigid manner. It will be noted that the strands 5 have portions of their length engaged with the strips 3, consequently holding said strips in proper position relative the posts l.

After the posts lhave been properly positloned, the mold 6 is applied, this mold consisting of boards 7, which are of such length as to it snugly between a pair of the posts 1, and with the outer faces in a plane with the inner faces of the posts. ATo prevent the boards 7 from moving inwardly between the posts l vertical cleats 8 are provided for engaging the .inner faces of the posts 1, as clearly shown in Figure l of the drawing.

, The mold 6 consists of side boards 9 which are secured to the posts 1 by nails 10, and it w1ll be noted that the boards 9 are so nailed as to be spac from the adjacent faces of the posts pear later. V

In Figure 2 of the `drawing the posts 1 are arranged for forming a support for the corners of a building wall, the only diierence in this structure over that shown in Flgure 1 is that the strips 3 are eliminated upon one side of the posts, and it will be noted that the manner of attaching the tie 4 is substantially the same.

Assuming that cement has been poured into the mold it will be obvious that it will settle as shown in a portion of Figure l 1, the purpose of which will ap-- of the' rawing, and since the nails 10 support the boards 9 in spaced relation with theposts 1,-it is obvious that when these boards are removed that the 'cement vwill remain as shown, and it will be noted that the tie 4, strips 3 and the major p ortion of the posts 1 are imbeddedin the cement. Upon removing the boards 7 the inner end. of the posts 1 will projectbeyond the wall face, a distance corresponding to the thickness of said boards. This is illustrated clearly in Figure 2, of the drawing wherein the posts 1 have .their inner Vends projected inwardly of the inner face of the wall 11,

llrwhereupon the laths 12 `can ,be 'nailed or otherwise secured to the inner faces of the posts 1, thereby producing an' air chamber 13. It will be of course understood that the nails 10A used for supportingk the boards 9 will be removed with-the boards.

In Figure 4 of the drawing the wall isshown with airv inlets 14, which are tapered and inclined downwardly and noutwardly,

the inner ends of said openings communin eating with the air chambersl so as to permit afree circulation of air in-said chambers. By inclining the openings 14, as shown, it is obvious that rain water cannot flow uplwardly therein and into air space 13.

In Figure y5 of the drawing there is shown a slightly modified form of the invention,

this form being designed to eliminate a number of the posts 1, so that a wall can be built at a smaller cost,.and in this instance uprights 15 are ern lo ed and are placed against the inner a'ce of the Wall. 11`after which the wire loop 16, engaged theref around, said loop being connected with the central portion of the tie 4. This loop 16 is twisted into engagement with thestrandsv 5 of the tie 4 which remain spaced afterthe tie Wires have been twisted to rmly hold the posts 1. in place, and since the tie 4 is imbedded in thel wall 11 and the loop 16 partially imbedded therein, it will be apparent that the loops will be firmly secured so as to hold the upri hts 15 in tight engagement with the inner ace of the wall 11. These uprightsare/of the same width as to have about each other between the their inner faces in a plane with the inner lfaces of the, posts 1 after which the laths 12 materialwhich will prolong the lives of these parts. This is deemed essential since the cement poured is in a moist state, and consequently by coating these parts with water proofing material the life thereof will 'be prolonged indefinitely.

What I claim is:

1. In a structure of the class described, a cement wall, -a plurality of vertically eX- tending posts imbedded in the wall, said posts havin spaced bores formed therethrough, horlzontally extending wire strands passing through said bores, and twisted posts.

2. In a structure of the class described, a cement wall having a continuous outer survface, a plurality of posts embedded in the wall, 'said posts having\ strips interlocked with the wallthe inner nfaces of said posts l extending beyond the inner surface of the wall, and wire strands passing through the posts and having portions thereof ,enga'ged with the strips, said strands being twisted together intermediate the posts.

` 3.. In a structure of the class described, acement wall, a plurality of posts imbedded in the wall, strips en ged with the sides of the posts, a pair of wire' strands, portions of said strands passing through the posts, and engageable with the strips to hold the same in mutual contact withV the posts, said strands being twisted together intermediate the posts.-

In testimony whereof I aHiX my signature.
